    Investigate Nasal Colonize Staphylococcus Species Biofilm Produced
    (Journal of Clinical and Analytical Medicine, 2015) Demir, Cemil; İnanç, B.B.
    Aim: 127 S.aureus and 65 CoNS strains were isolated from patients noses’. To produce a biofilm ability was investigated using three different methods. Slime-positive and negative staphylococcies’ resistance were evaluated against different antibiotics. Material and Method: Swap samples puted 7% blood agar. Staphylococcus aureus and coagulase-negative staphylococci (CoNS) isolates biofilm produced ability were investigated using Congo Red Agar (CRA), microplates (MP) and Standard Tube (ST) methods. In addition to that, presence of antibiotic resistance of the staphylococcal isolates are determined agar disc diffusion method. Results: The rate of biofilm produc-ing Staphylococcus spp strains was found to be 72.4%, 67.7%, and 62.9%, respectively with CRA, MP, and ST tests. There was no significant relationship among the tests (p>0.05). In addition, antibiotic resistance of Staphylococcus spp. against various antibiotics was also determined by the agar disk dif-fusion method. Resistance rates of biofilm positive (BP) Staphylococcus spp for penicilin G, ampicilin, amocycilin/clavulanic acid, tetracyclin, eritromycin, gentamycin, and enrofloxacin 71.7%, 69.7%, 6.2%, 20.7%, 21.4%, 1.4%, and 0.7%, respectively. Resistance rates of biofilm negative (BN) spp for 42.6%, 23.4%, 4.3%, 14.9%, 19.1%, 0.0%, 0.0% respectively. All Staphylococcus isolates were found to be susceptible to vancomycin and teicaplonin. Although BP strains antibiotic resistance rates were observed higher than BN strains. But resistance rates were not found statistically significant (p>0.05). Discus-sion: CRA is the reliablity and specifity method to determine Staphylococcus spp. biofilm produce ability. © 2015, Journal of Clinical and Analytical Medicine. All rights reserved.

    Investigation of Uroprotective Effects of Seed Methanol Extracts of Hypericum Triquetrifolium Turra. on Cyclophosphamide-Induced Bladder Hemorrhagic Cystitis and Nephrotoxicity in Wistar Albino Rats
    (Cukurova Univ, Fac Medicine, 2020) Keskin, Cumali; Keskin, Cumali; Sahinturk, Varol; Ayhanci, Adnan
    Purpose: This study investigated the possible uroprotective effects of Hypericum triquetrifolium Turra. (HT) seed methanol extracts (25,50,100 mg/kg, i.p., for 6 days) against cyclophosphamide (CYP)-induced (150 mg/kg, single dose, i.p.) acute bladder hemorrhagic cystitis (HC) and nephrotoxicity in rats. Materials and Methods: Wistar albino rats used in this study were divided into nine groups, each including seven rats. Group 1 (control) was treated with 0.5ml saline (SF) and Group 2 was treated with CYP (150 mg/kg). Groups 3, 4, 5 were treated with 25, 50, 100 mg/kg HT, respectively while groups 6, 7, 8 were treated with 25, 50, 100 mg/kg CYP + HT, respectively. Finally, Group 9 (control-2) was treated with 0.5ml-%0.2 dimethyl sulfoxide (DMSO). The serum creatinine, blood urea nitrogen (BUN), superoxide dismutase (SOD) and catalase (CAT) levels were measured in blood serum. Results: The CYP-treated rats histopathologically had mild-moderate bladder and renal injuries. The serum creatinine and BUN levels, which are the biochemical markers of renal injury, significantly increased compared to the control group. Conclusion: HT showed a protective effect on CYPrelated bladder HC and nephrotoxicity in rats by inhibiting inflammation and apoptosis.

    Study of Endogenous Paramagnetic Centers in Biological Systems From Different Areas
    (John Wiley and Sons Inc, 2021) Nasibova, A.; Khalilov, R.; Abiyev, H.; Kavetskyy, T.; Trubitsin, B.; Keskin, C.; Eftekhari, A.
    Plant leaves (Eldar pine (Pinus eldarica M.), fig (Ficus carica L.), and olive (Olea europaea L.)), collected in territories with different ecological conditions, of the Absheron Peninsula (Azerbaijan Republic) were studied by electron paramagnetic resonance spectroscopy (EPR). The generation of nanophase iron oxide magnetic particles in biological systems under the influence of stress factors was revealed. It was found that the process of biomineralization plays a role in the formation of biogenic iron oxide magnetic nanoparticles in plants and the generation of magnetite crystals in biological tissues, and stress factors have a stimulating effect on this phenomenon.
